About Penray
About Penray
The Penray Companies was founded in 1951 in Wheeling, Illinois, building its business on aftermarket chemical solutions for vehicles. From those modest beginnings, Penray grew into an industry leader manufacturing and marketing aerosol, liquid, and other chemical products for the automotive, heavy duty, marine, industrial, agricultural, and powersports end markets.
Penray's core offerings span fuel treatments, coolant solutions, lubricants, sealers, and specialty cleaners, developed to address complex vehicle maintenance challenges across a wide range of equipment types. That breadth has let fleets and repair shops rely on Penray for both common maintenance chemicals and more specialized treatment products.
After operating under three private investors, Penray was acquired on June 1, 2017 by PLZ Aeroscience Corporation, a company majority owned by Pritzker Group Private Capital, and continues to manufacture from two facilities in Illinois. ChatMRO's catalogue covers Penray's fuel treatments, coolants, and sealers by vehicle type so fleet managers can match the right chemical to their maintenance need.
